Default sizes - why so small?

As I get more into Unity I’m finding myself with more questions. Please bear with me.

I’m wondering why Unity works with such small sizes. For example, throwing a cube into the world creates a 1x1x1 cube. 1 unit on all dimensions? And a light defaults to 10 units in radius, etc.

Are these small sizes for a reason - like physics stability - or is it something else?

I suppose this might be the Mac standard as Cheetah 3D seems to work this small by default as well. I guess I’m using to PC editors that seem to default to larger world resolutions.

Just wondering!

By default we consider one unit to be 1 meter. You can work in another resolution if you like…

Well, yes and no. Is there a way to override those default settings for things like light radii and cube meshes? If not, working in another resolution would be a tedious pain.

But I don’t have a problem with it, it’ll just take some getting used to. Thanks!

Indeed, 1 meter is a good scale for most games, I think. Probably you’d use it as a reference or a temporary stand-in for something, or at least that’s what I do, so having something where you can quickly see a 1-meter object is useful. You wouldn’t actually use it for anything permanent in a real project (unless you’re doing something highly abstract, I guess). You would of course just use prefabs for objects that have specific settings you want to keep using, so you don’t have to keep manually adjusting settings for anything if you don’t want to.
